maximize the target to clutter ratio (TCR) metric, which represents the first use
of the TCR loss function for detecting moving objects. To further challenge the
MTINet, we also evaluated its performance with simulated sensor movement
mimicking effects of image stabilization processes. Finally, we also propose a
modification of the Reed-Xiaoli detector (originally developed for anomaly
detection in hyperspectral data) to enable it to detect temporal anomalies
caused by moving objects and refer to it as the temporal anomaly Reed-
Xiaolis (t-ARX) algorithm. We find that the t-ARX algorithm can achieve better
probability of detection at lower false alarm rates, while the MTINet is superior
at finding difficult targets at higher false alarm rates. We then show that the
combination of the two algorithms achieves the best overall performance.
